SPECIFICATION forming part of 'Letters Patent No. 602,376, dated April12, 189s.

To all whom t may concern:

Beit known that I, JOHN THOMSON, a dciti-v zen of the United States,residing at Brooklyn, in the county of Kings and State of New York, haveinvented certain new and useful Improvements in Mechanism forControlling the Action of Oscillating Disks, of which'the following is aspecification.

My invention relates to mechanism for controlling the action ofoscillating disks, and is an improvement upon or an extension of thedevice described and claimed in my patent ofy mit the disk to leave thefrustunis 2O of the April 27, 1897, No. 581,630.

Thus my invention consists in the various features of construction andarrangements of parts substantially as hereinafter more fully set forth,in which connection it may be said-v that the arrangement is especiallydesignedv to be used in connection with disk Water-me ters.

In the accompanying drawings, Figure lis a vertical section of adisk-chamber casing suitable for a water-meter, showing the essentialfeatures of my invention. Fig. 2 is a sectional diagram illustrating thedetails of construction and the principles of operation. Fig. 3 is adetail view to illustrate a method of constructing the conicalthrust-block, and Figs. 4, 5, and 6 denote modifications in theconstruction.

Referring to the embodiment of my invention illustrated in the drawings,the diskchamber casing is formed of the upper and lower sections 5 6,containing the disk 7 and ball 8.

The controlling device consists of the spindle 9, having a bearing 10through the ball, and the conical thrust-block 12, connected to thespindle and having ay conical bearing 13' in the interior of the casing.v

The foregoing coincides with the broad elenecessary.

The conical thrust-block 12, instead of .hav-

ing its base formed to correspond to the spherical contour of the ball,has a flat-surface base 14, produced at a right angle to thethrust-resisting surface, as 15, Fig. 3. The advantage of this is toreduce the friction of Applicata had Mayr, i997; sena 110.635,541.(Numan.)

rotation betwixt the ball and the block, as the revolution is like thatof a collar or shoulder where the surfaces 1'6 of the block and ballimpinge. Moreover, as the thrust-block is centrally supported over theaxis 17 of the spindle anywear at the shoulders 16 willnot affect theperformance of the thrust-block in .that the thrust-resisting surfaces,as arrows 1S, lie in a plane, as 19, parallel to that of the axis 17 ofthe spindle. Hence downward movement of the thrust-block in thedirection of the axial line of thespindle will not pervdisk-chamber. f A'consideration of the foregoing shows that the opposite and surroundingsurface of the thrust-block does not play an important part.

Hence, if desired, it may be partially removed or even considerably so,as shown at 22, Fig.

`4,Wl1ere the actual bearing-surface of the device, the thrust-blockbearing 27 should be adjustable, as by the threaded portion 28,

and also removable in a line 29 at a right angle to the medium plane 30ofthe disk-chamber. So, too, the lower socket-bearing 31 for the ballshould be capable of adjustment vertically, as by the screw-threads 32.

With the foregoing arrangement of parts A`the Vcenter 33 of the ball maybe readily main- ,tained in the plane 30of the disk-chamber,

a position essential to the best operation. Thenthe thrust-block bearingmay be screwed tact between the thrust-resisting surfaces 18,

VFig.``2, which in turn will produce a similar result with respect tothe disk and the frustums of the chamber. A contingent advantage is thatby entirely removing the thrustblock bearing 27 the thrust-block,together with its spindle, may also be withdrawn or inserted withoutseparating the sections of the chamber.

.-down to bring any desired intimacy of cona ICO Vhen parts are firstassembled, the construction of the socket-bearing 3l should be such thatwhen it is adjusted to afford a proper bearing to the ball its beveledface 35, Fig. 4, shall not come up flush with the face of the frustum20, as indicated in an exaggerated degree by the dotted line 36. Inactual practice it is sufficient if the said beveled face of the socketshall come up Within a few thousandths of an inch of the face of thefrustum, thus not forming a leakage-space suliicient to cause anyappreciable fault in registration. When so arranged, any subsequent Wearof the ball and socket may be taken up without setting the face 35beyond the surface 36 ofthe frustums. In this Wise any Wear of the partstending to lower the disk and ball in the direction of the verticalcenter 29 may be accurately and conveniently corrected Without danger oftilting or tending to tilt the disk away from the frustums.

Figs. 5 and G denote a further extension in the detail of constructionover that shown in Fig. et, but Without departing from the spirit andessence of my invention. Thus in these figures the thrust-block isrepresented as but a piece of Wire 2, formed to lie parallel With theaxis 17 of the ball-spindle, and except in the element oi' extent ofbearing-surface afforded at the line of Contact betwixt the cylindricalblock and its conical bearing, as at 1S, this alteration, modification,or development of the initial invention will prove effective inpractice. Hence it is that I disclaim any intention of being strictlybound to the precise limits of the drawings or to the exact terms hereinemployed to describe the said drawings.

"What I claim isl. The combination with the casing, disk and ball, ofthe thrust-block resting upon the ball, and having its base formed flatand to a right angle to the thrust-resisting surfaces.

2. The combination with the casing, disk, ball and conical thrust-block,of a bearing for said thrust-block capable of adjustment in thedirection of the axis of the cone, substantially as set forth.

3. The combination with the casing, disk and ball, of the thrust-blockand the adjustable bearing therefor, both of which are adapt.- ed to beremoved from the exterior of the disk -chamber casin g, substantially asdescribed.

4. rlhe combination with the casing, disk and ball, of thevertically-adjustable bearing having its exposed beveled face 35, setbeneath the face of the frustum.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing Witnesses.

JOIIN THOMSON.
